Aimed at characteristic of ambiguous relationship among entities in P2P network

as foundation of fuzzy inference theory

a fuzzy proposition deduction system was given

also a trust recommendation and comprehensive evaluation model in P2P network based on triple I fuzzy inference algorithm was built. In this model

fuzzy reasoning was on the basis of multiple recommendation rules

it had achieved the comprehensive evaluation of recommendation trust

established a new trust model in P2P network environment. The results of simulation experiment show that this model can increase the success rate of transaction greatly

and make it possible to establish trust relationship between peers more ef-fectively.
